. The invention relates to containers for cor- -rosive-liquids 'such as hydrouoric acid, and ymore particularly to bottles from which the corrosive liquids may be dispensed, for `in- 5 stance, in'laboratories, drug stores, and the like.A The invention has forits object to provide a container in the form of a bottle made of wax and reinforced in a novel manner to maintain the body of the 'bottle in an upright 10 position in temperatures tending to soften the wax. A further Object of the invention is to provide a bottle of thisdescription; the neck of which is constructed in a novel manner to rovide one or more pouring channels in the repthereof to direct the liquid, which does not wet the wax surface, ina definite stream.

Other objects will appear from the descrip-,-

tion hereinafter and the features of will be pointed out in the claims.

Reference is had to the accompanying drawings which illustrate an example of the invention without defining its limits Aand in which Fig. 1 is an exterior elevation of the novel bottle, Fig.l 2 is a vertical section on the novelty 'I 2q. line 2-2 of Fig. 1, Fig. 3 is a plan view` of the bottle, Fig.n 4 is a horizontal section through the neck. thereof on the line 4&-4`of Fig. 1, and Fi' 5 is av horizontal section through the` body of the `bottle on the line 5-5 of Fig. 1.

' As shown in the drawings, the bottle come rises a body and a continuing neck 11, both of which are made of wax, the body l() beingshown of cylindrical form; it will be understood that this form may be changed if 35 for any reason this should be desired. The

means body 10 is provided with a reinforcing own-1n which, in the illustrated example, is s `the form of a'tube or cylinder 12 of paper or other suitable materialpossessing an"in- 40 herent rigidity sufficient to maintain .the body 10 in an uprighty Osition ifthe wax, ofwhich the body 1s', may ecome soft from any cause.

The tube or cylinder 12 or equivalent rein-- forcing means yisinmolded connection with the body and extends lengthwise thereof throughout substantially its entire length, as shown in Fig. 2. It will be noted from this L, illustration that aJl of the reinforcing c lindoris spaced from the inner surface o the container and protected, therefore, from the corrosive li uid. In the preferred form, the tube12, whi corresponds in shapeto the form of the body 10, is in external molded connection with the body or, inother words, surrounds the same as shownin Fig; the

aforesaid tube or cylinder 12 thus comprises v the external surface of the body 10 and accordingly may have advertising matter or other data produced directly upon its outer surface by printing or Otherwise or by pasting suitable labels upon such outer surface. In any case, an acid-proof coating 13, preferably comprising a coating of transparent paraflin,

the purpose of closing'fthe, bottlef To insure a tight lit for the stopper 16, which is preferab y tapered, the bore may be flared in the drawings, the stopper has the usual mushroom top which.- ma be reversed and 80 Outward slightly at-itsexit end.' As shown sealed over the exit end o the bore upon the f end face of the neck by means of a hot wire when the bottle is filled; the latter is thus effectively sealed during storage or shipment. When removal of the stopper is desired,'a

similar hot wire may be utillzed to break the connection between said stopper 4and the end face of the neck and to permlt the stopper to be utilized in the regular way. 1

Any suitable method may be 'followed inl manufacturing bottles of .the indicated kind, the followingmethod having been utilized and found successful. The einfo'cing means "sorted into'a brass or other conventional mold in which the bottle is to be molded so as vir-- tually to constitute a liningfo'r said mold.

.or specifically the tube or cylinder 12is ini The wax is then poured into the mold to mold the bottle in the customary manner and to Aproduce the body 10 and continuing neck 11 Vand at ther same time to embed the tube or l'L inder 12 in the Ybody 10 so as to externa y surround the same. VAt the proper time, the molded bottle with -the tube or' cylinder in molded connetion therewith is removed from.

covers the tubel cylinder 12 so as to protect -it against t destructive action of any cor- 65 rosive l d or acid which may spill or run the mold and is di ped .in an acid-resistant material such as a airly transparent parain 'y solution to provide, the protecting coating 13.

It will, of course, be understood that if the advertising matter or other data is tobe directly .produced upon the external surface of the tube or cylinder 12, this will be done at -a proper time'and in a proper manner prior to the insertion of the tube or cylinder into equivalent.

said saggingJor bending over is entirely prethe mold. If the advertising matter or other data isin the form of labels, these maybe pasted or otherwise `attached to the cylinder either prior to its insertion into the mold or subsequently to the molding of the bott-le therein; in the lattercase, the labels, of course, are secured in place prior to the dipping of the bottle into the parafin solution or its The Wax bottles for hydrofluoric acid and other corrosive liquids. when allowed to stand on a laboratory sheli` during the summer vented. ottles of the indicated type, considerable difficulty has been experienced in directing the flow of liquid from the neck of the bottle, which constitutes a decided disadvantage because of the injurious and harmful characteristics of the corrosive liquids,

. such as hydroluoric acid. With. the present arrangement, this diicultyand these disadvantages are overcome byA providing thev pouringchannels 15, which not only make it possible positively to direct and control the p iow of t e liquid, but make it possible also to pour out the contents in the form of drops, if this should be desired.-

It will be understood that-the term wax as .used inthe description, is intended to cover ceresine and other 'lvvairesl or' any 'i material Whlch may comprise an'equiyalent thereof, and which tends to soften or otherwise lose its inherentl rigidity in normally high temperatures.

The term claims in connectionwith `the angularity of the pouring channels is to beunderstood* to mean that the sharpness of the angular channel Within the neck of the bottle is tol be de-l termined by the character of the liquid which the bottle is to contain and will be governed bythe surface tension and viscosity of such liquid and thc readiness with Which `or the eX- tent tov which the latter Wets the inner Wax` vsurface of lthe Aneck of the bottle.

Various changes in the specific forms shown relatively as employed in the and described may be made Within the scope pot-the .claims Without departing-fibrin the vspirit of' the invention. y

1. A bottle for containing acids-and the 'like comprisingja cylindrical body and a lneck of Wan, and arelatively rigid and'heat resisting reinforcing cylinder inset in said body and in molded connection'with, and

spaced from the inner surface of, said body for maintaining the latter in an upright position at temperatures at which the iwax tends to soften. l

2. A bottle for containing acids and the like comprisin a bod and neck of Wax, the neck havingagb so shaped as to provide a relatively sharp angular channel for directing the flow of liquid lfrom said bottle. H y

'3. A bottle for containing 4acids andthe like comprising abodyand neck ofwax, the neck having a bore, the exit end of which is of rectangular cross-section to provide relatively sharp 'angular' pouring channels located.` in pairs at diametrically opposite said jbottle.
